Did it lower itself to entry/exit mode? You may have discovered the feature that everybody's been looking for. There was supposed to be a selection in the EVIC to have the car lower automatically after being put in park. So far I don't think anybody has found it.

Next time you're in the Jeep, could you check the suspension settings and see if there are any options. When was your Jeep built?

My wifes 2011 did the same thing and our 2014 is no different. Lowers itself a bit after it is turned off. However when it does lower when off it does not lower it all the way to the "entry/exit height"
